EXAMPLE 18

To 1 g of heptakis(6-benzoylamino-6-deoxy)-β-cyclodextrin was added 75 ml of pyridine and 3.6 g of sulfur trioxide-pyridine complex was further added thereto. After reaction at 70° C. for 6 hours, the supernatant was removed and the residue was treated with methanol and ethanol for pulverization. The obtained powder was collected by filtration, dried and then dissolved in 5 ml of water. A 30% aqueous sodium acetate was added to the solution to give a sodium salt, followed by purification on a column packed with Sephadex G-10 (trade name, manufactured by Pharmacia AB) to give 0.87 g of sodium salt of heptakis(6-benzoylamino-6-deoxy)-β-cyclodextrin polysulfate as a light brown powder.

EXAMPLE 41

To 0 5 g of heptakis(6-benzenesulfonylamino-6-deoxy)-β-cyclodextrin was added 30 ml of pyridine, and then 1.6 g of sulfur trioxide-pyridine complex was added thereto, followed by stirring at 70° C. for 6 hours. After completion of the reaction, the supernatant was removed, and the residue was washed successively with methanol and ethanol to give a powder. The powder was collected by filtration and dried to obtain a brown powder. The powder was dissolved in 3 ml of water, and the pH of the solution was adjusted to 8 with a 10% aqueous sodium hydroxide, followed by purification on a crosslinked dextran gel: Sephadex G-10 column (trade name, manufactured by Pharmacia AB) to give 0.7 g of sodium salt of heptakis(6-benzenesulfonylamino-6-deoxy)-β-cyclodextrin.polysulfate as a white powder.

EXAMPLE 42

In 85 ml of pyridine was dissolved 0.83 g of mono(6-benzenesulfonylamino-6-deoxy) -β-cyclodextrin with heating at 100° C., and 6.2 g of sulfur trioxide-pyridine complex was added thereto with stirring well, followed by stirring at 100° C. for 6 hours. The pyridine was removed by evaporation, and the residue was dissolved in 20 ml of water and 40 ml of methanol, followed by further addition of 300 ml of methanol. The resulting mixture was allowed to stand overnight at a cool place, and the precipitates thus formed were collected by filtration, washed with methanol and dissolved in water. The resulting solution was concentrated to evaporate the methanol contained therein. Water and 50 ml of a strongly acidic ion exchange resin S-lB(H+) (trade name, manufactured by Mitsubishi Kasei Corporation) were added to the residue, and the resulting mixture was stirred at room temperature for 30 minutes. The resin was removed by filtration from the mixture, and after the pH of the filtrate was adjusted to 7.3 with 1.7 N potassium hydroxide, the filtrate was filtered through a membrane filter, followed by freeze drying to give 2.0 g of potassium salt of mono(6-benzenesulfonylamino-6-deoxy)-β-cyclodextrin.polysulfate as a white powder.

EXAMPLE 55

To 0.9 g of heptakis(6-benzylamino-6-deoxy)-β-cyclodextrin was added 60 ml of pyridine, and then 5.13 g of sulfur trioxide-pyridine complex was added thereto, followed by reaction at 70° C. for 6 hours. The supernatant was removed from the reaction mixture, and the residue was treated with methanol to give a powder. The powder was collected by filtration, dried and then dissolved in 10 ml of water. After the pH of the resulting solution was adjusted to 8 with a I0% aqueous sodium hydroxide, the solution was purified on a column packed with Sephadex G-10 (trade name, manufactured by Pharmacia AB) to give 1.17 g of sodium salt of heptakis(6-benzylamino-6-deoxy)-β-cyclodextrin polysulfate as a light brown powder.

(1) In 1.2 l of pyridine was dissolved 114 g of β-cyclodextrin, and under stirring of the resulting solution with ice cooling, 52 g of 2-naphthalenesulfonyl chloride was added thereto. After the reaction mixture was stirred at room temperature for 24 hours, water was added thereto to quench the reaction. The solvent was removed from the reaction mixture, and 1 l of water was added to the residue, followed by heating. The supernatant was decanted off, and the caramel-like substance thus obtained was washed with water and then dissolved in 1.5 l of a 70% aqueous methanol with heating. The resulting solution was concentrated to about 1 l, and the precipitates thus formed were collected by filtration. The precipitates were dissolved again in a 70% aqueous methanol with heating, and after the insolubles were removed by filtration, the filtrate was left to stand to allow crystallization. The crystals formed were collected by filtration and dried to give 23 g of a mixture of tris(6-O-naphthalenesulfonyl) -β-cyclodextrin/tetrakis-(6-O-cyclodextrin=1:1 as a white powder.

REFERENTIAL EXAMPLE 80

(1) In 600 ml of pyridine was suspended 39.1 g of a dried γ-cyclodextrin, and 26 g of mesitylenesulfonyl chloride was added thereto under stirring at room temperature, followed by stirring at room temperature overnight. Water was added to the reaction mixture and the mixture was evaporated to remove solvent. The residue was washed with water and then with ethanol. The resultant powder was collected by filtration, and dissolved in methanol. The solution was applied onto a column packed with CHP-20 RESIN (trade name, manufactured by MITSUBISHI KASEI Corporation), and the column was washed with 50% methanol and then with 65% methanol. Then, 80% methanol was passed through the column to elute tris(6-O-mesitylenesulfonyl)-γ-cyclodextrin, and then methanol was passed through the column to elute tetrakis(6-O-mesitylenesulfonyl)-γ-cyclodextrin.

(2) The 80% methanol eluate was evaporated to dryness, and the residue was dissolved in methanol. The solution was applied onto a column packed with CHP-20 RESIN (trade name, manufactured by MITSUBISHI KASEI Corporation), and the column was washed with 70% methanol. Then 80% methanol was passed through the column to collect three fractions (fraction A, B and C).

The retention time of each fraction was examined by high performance liquid chromatography. The results are as follows.

Fraction A; (retention time) 7.4, 9.0, 9.5, 11.5 (min)

Fraction B; (retention time) 11.6 (min)

Fraction C; (retention time) 7.4 (min)

Each of fractions was evaporated to dryness, whereby the following products (i.e., region isomers of tris (6-O-mesitylenesulfonyl) -γ-cyclodextrin.) were obtained as colorless powder.

On the other hand, the methanol eluate obtained in paragraph (1) was evaporated to dryness. The residue (i.e., crude tetrakis(6-O-mesitylenesulfonyl)-γ-cyclodextrin were dissolved in 100 ml of pyridine and 7.2 g of mesitylenesulfonyl chloride were added thereto. The mixture was stirred at room temperature for 2 days. Then, the reaction mixture was evaporated to dryness, and the residue was purified by silica gel column chromatography to give 0.93 g of octakis(6-O-mesitylenesulfonyl)-γ-cyclodextrin as colorless powder.

m.p. 230° C. (decomposed)

(3) To a mixture of 0.49 g of benzylmercaptane, 10 ml of N,N-dimethylformamide and 0.17 g of 60% sodium hydride was added 1.0 g of tris(6-O-mesitylenesulfonyl)-γ-cyclodextrin (obtained from fraction A). The mixture was stirred at 80° C. for 2 hours. After cooling, water was added to the mixture, and the precipitates were collected by filtration and dissolved in methanol. The methanol solution was treated with activated charcoal and then condensed. Acetone was added to the residue, and the precipitates were collected by filtration. The crude product (0.51 g) thus obtained was dissolved in N,N-dimethylformamide, and the solution was applied on a column packed with Sephadex G-25 (trade name, manufactured by Pharmacia AB). The eluate with N,N-dimethylformamide was evaporated to dryness, and the residue was washed with acetone and then dried. 0.28 g of tris(6-benzylthio-6-deoxy) -γ-cyclodextrin was obtained as colorless powder.

TEST EXAMPLE HIV Proliferation Inhibitory Action Principle

It is known that when MT-4 cells, which are sustaining infectious cell line of human T-cell Leukemia virus I type [HTLV-I], are infected with HIV, HIV proliferates rapidly and the MT-4 cells are killed in 5 to 6 days due to the cellular damage. Therefore, HIV proliferation inhibitory action can be evaluated by examining the number of vial cells of the MT-4 cells infected with HIV.

Procedure

MT-4 cells were infected with HIV (a culture supernatant of TALL-I/LAV-I) at 37° C. for one hour so that TCID₅₀ (median tissue culture infectious dose)/cell might be 0.001, followed by washing with the medium. The infected MT-4 cells were then suspended at a concentration of 1×10⁵ cells/ml in RPMI-1640 culture media [containing 10% of FCS (fetal calf serum)] containing samples of various concentrations respectively. Each of the thus obtained cell suspension was introduced in a flat-bottom culture plate and was incubated at 37° C. in the presence of 5% carbon dioxide for 5 days. After incubation, the number of viable cells in the cell suspension was counted by the Tripan-Blue Staining Method. The HIV proliferation inhibitory action of the sample was evaluated in terms of the concentration of the sample which suppresses by 100% (completely) the infectiousness and the cell modification action of HIV.

Results

The results are shown in the following Table 16.
